define Package/net-snmp/Default/description
 Simple Network Management Protocol (SNMP) is a widely used protocol for
 monitoring the health and welfare of network equipment (eg. routers),
 computer equipment and even devices like UPSs. Net-SNMP is a suite of
 applications used to implement SNMP v1, SNMP v2c and SNMP v3 using both
 IPv4 and IPv6.
